BUBBLER DRINKING-FOUNTAIN.

tains,and particularly to fountains of the bubbler type.

One of the objectsof this invention is to provide a fountain which may be used in schools, and public places, in whicha plurality of bubbler jets are mounted upon a common supply pipe;

And a further object is to so construct these nozzles that the jet issuing therefrom will have more the form of the mouth than jets ordinarily issuing from these bubbler fountains.

A further object is to provide a fountain of this kind in which the supply valve is held closed, or nearly closed when the fountain is out of operation.

And still a further object in this connec tion is to provide means for regulating the amount of closing movement of the valve, so that a small amount of water maybe allowed to issue from the bubbler nozzle when the valve is in its almost closed position, and provide means for regulating the opening movement of the valve so as to prevent too great a discharge of water from the bubbler nozzles.

Still another object is to provide means for preventing trash from passing down into the discharge pipe and thus obstruct the outflow of water and also to prevent trash from being disposed so as to impede the flow from the bubbler nozzles.

Other objects have to do with the details of construction and arrangement of parts as will hereafter more fully appear.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a longitudinal sectional View of a drinking fountain constructed in accordance with my invention;

Fig. 2 is a top plan view of theconstruction illustrated, in Fig. 1, the parts being broken away;

Fig. 3 is a side elevation of one ofthebub bler nozzles, the allied portions of the fountain structure being in section;

Fig. 4. is a vertical sectional view on the line 44 of Fig. 3;

Fig. 5 is a vertical sectional view of a modified form of fountain wherein only one bubbler-nozzle is used; and

Fig. 6 is a top plan view of the construction illustrated in Fig. 5.

Referring to these drawings, and particularly to Figs. 1 and 2, 10 designates a rela tively large vertically disposed pipe, which at its upper end carries the lower bowl shape section 11 of a housing for the several bubbler jets. Extending up through the center of the pipe 10* is a relatively smallsupply pipe 12, which is rotatably mounted in any suitable manner in a bearing 13 at its lower end, this supply pipe at its lower end carrying a valveld, operating within a valve casing 15, which forms partor is joined to the lower end of the pipe section 10. This valve 14 has a central vertically extending passage alining with the pipe 12 and a laterally extending port 16 and also a discharge port 17,disposed preferably at right angles to the port 16 and discharging into a waste pipe 18. The port 16 is, of course, connected to a supply pipe. The upper end of the pipe 12 is rotatably mounted in a metallic cap 19, which is preferably concavo convex and extends downward and then is extended radially in the form of radially disposed bars 20. The outer ends of these bars are curved upward and over the curved rim 21 of the basin shaped section or bowl 1.1 and are provided with bolts22 passing through slots 23 formed in thisrim 21. The purpose of these slots will be later stated.

Attached to the pipe 12, at its upper end, and extending radially therefrom, are a plurality of discharge pipes 24, these pipes being upwardly turned at their extremities andformed with bubbler nozzles 25. These upwardly turned extremities of the pipes 24; extend upward through the space between the arms or bars 20. Mounted upon the pipes 24 and rotating therewith is a perforated screen 26, which at its outer edge is bent upward and outward so as to conform approximately to the shape of the rim21 and the inner marginof this disk is turned upward as at 27 within the shield 19 and to ill be obvious that a rotation of the I provide the springs 28, these springs being attached to the pipes 24 in any suitable manher and being attached at their other ends to the arms or bars 20 in any suitable manner. I do not wish to be limited to this particular arrangement of springs, as others may be used for the purpose, but I have found this arrangement particularly effective and simple. The springs are concealed beneath the strainer plate 26 and, therefore, cannot be tampered with. The pipe 10, just above the bearing 13, is connected by a port 29 to a drain pipe 30, the port 29 constitut ing a drainage opening.

In Fig. 5 I show another form of my device which embodies the same principles as those illustrated in Figs. 1 and 2 and in this figure, 31 designates the outer discharge pipe having a drainage opening 32 and formed at its upper'end with a flange 33 and a laterally disposed lip 34. A cap 35 is attached to this flange 33 and forms a bearing for the upper end of the supply pipe 36, the lower end of which is provided'with the same valve structure as that illustrated in Fig. 1. This cap 35 is provided for a portion of its circumference with a slot 37, defined. by the two shoulders 38. The supply pipe'36 at its upper end is laterally bent and then upwardly extended as at 39 and provided with the bubbler nozzle 40. A spring 41-acts to shift the supply pipe 36 to a position to nearly cut off the flow of water to the supply ipe, but it is obvious that the supply pipe may be shifted by taking hold of the branch 39 and shifting it to a position to permit the discharge of water from the nozzle. The degree of discharge from the bubbler nozzle and the degree of cut off may be regulated by shifting the cap 35 around upon the flange 33, the cap 35 being provided with a plurality of recesses 42 on its ment of the bubbler. A hook 44 may margin through which'the bolts 43 may be disposed and thus the adjustment of this cap will limit the extent of opening of the bubbler and the extent of the closing movebe provided to hold the bubbler in its fully open position. to

The use of the construction illustrated in Figs. 5 and 6 will be obvious, but in the use of the'device shown in Figs. 1 and 2, the pipe 12 'is rotated to its relatively fully opened position by means of handles 45, which may conveniently be attached to the perforated plate 26, these handles extending out over the rim of the basin 11. By reference to- Fig. 3 it will be seen that I have provided a particular form of nozzle. The upper end of each pipe 24 is upwardly flared and made slightly bulbous, as at 16 and formed with a longitudinally extended slit 47, which causes the water ejected from the nozzle to take the form of a relatively elongated sheet instead of a rounded bubble. Thus this form of jet is more convenient for drinking purposes, as the person drinking does not have to cause his mouth to conform to the shape of the bubble.

WVhile I have illustrated four arms 20, I wish it understood that more arms may be used and that I have only illustrated four arms so as to prevent the drawing from being obscured. By using more arms 20, it is obvious that a less amount of rotation will have to be given to the pipe 12 in order to open or close the valve 1 1. Of course, under these circumstances, the angular relation of the orts 16 and 17 will be changed to correspond;
